Ecology and Life History
Migration
false - false - true - Migrates primarily through western North America west of Rockies, less frequently (primarily in fall) east of Rockies (AOU 1983). Migrates northward to breeding areas, arriving late May-early June in northern Alaska. Southward migration usually begins in late July or early August, greatest numbers in August-September; juveniles begin migration after mid-August, rare before mid-September (Hayman et al. 1986). Rare but regular migrant in Hawaii.

Food Comments
Forages shallow fresh water and mud bars, probing into mud with bill. Feeds on insects and their larvae, mollusks, crustaceans, marine worms, spiders, and seeds of aquatic plants (bulrushes, pondweeds, sedges, etc.).
Reproduction Comments
Breeding begins in late May or early June (Harrison 1978); early nestings in northern Alaska in the first half of June. Clutch size is 4. At first both sexes take turns incubating the eggs; later only the male is involved. Incubation appears to last for 20 days. Precocial young are tended by male.
Ecology Comments
Little information on home range; in Siberia, nesting pairs remained in an area about 100-300 meters in diameter (Johnsgard 1981).
